前言
MariaDB数据库管理系统是mysql的一个分支,主要由开源社区在维护,采用GPL授权许可。开发这个分支的原因之一是:甲骨文公司收购了MySQL后,有将MySQL闭源的潜在风险,因此社区采用分支的方式来避开这个风险。[3]
MariaDB的目的是完全兼容MySQL,包括API和命令行,使之能轻松成为MySQL的代替品。在存储引擎方面,10.0.9版起使用XtraDB(名称代号为Aria)来代替MySQL的InnoDB
- # yum install mysql -y
- # mysql
- ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (111)
- 试着去启动mysql服务,仍然不行
-
- # systemctl start mysql
- Failed to issue method call: Unit mysql.service failed to load: No such file or directory.
-
- # systemctl start mysql.service
- Failed to issue method call: Unit mysql.service failed to load: No such file or directory

下面讲正确的步骤
- # yum install mariadb-server -y
- systemctl stop mariadb.service
-
- # systemctl start mariadb.service
- # systemctl enable mariadb.service
- # mysql
